The functions of the somatosensory system are multiple. We use tactile input to localize and experience the various qualities of touch, and proprioceptive information to determine the position of different parts of the body with respect to each other, which provides fundamental information for action. Further, tactile exploration of the characteristics of external objects can result in conscious perceptual experience and stimulus or object recognition. Neuroanatomical studies suggest parallel processing as well as serial processing within the cerebral somatosensory system that (...) reflect these separate functions, with one processing stream terminating in the posterior parietal cortex (PPC), and the other terminating in the insula. We suggest that, analogously to the organisation of the visual system, somatosensory processing for the guidance of action can be dissociated from the processing that leads to perception and memory. In addition, we find a second division between tactile information processing about external targets in service of object recognition and tactile information processing related to the body itself. We suggest the posterior parietal cortex subserves both perception and action, whereas the insula principally subserves perceptual recognition and learning. (shrink)

Colour has been shown to facilitate the recognition of scene images, but only when these images contain natural scenes, for which colour is ‘diagnostic’. Here we investigate whether colour can also facilitate memory for scene images, and whether this would hold for natural scenes in particular. In the first experiment participants first studied a set of colour and greyscale natural and man-made scene images. Next, the same images were presented, randomly mixed with a different set. Participants were asked to indicate (...) whether they had seen the images during the study phase. Surprisingly, performance was better for greyscale than for coloured images, and this difference is due to the higher false alarm rate for both natural and man-made coloured scenes. We hypothesized that this increase in false alarm rate was due to a shift from scrutinizing details of the image to recognition of the gist of the image. A second experiment, utilizing images without a nameable gist, confirmed this hypothesis as participants now performed equally on greyscale and coloured images. In the final experiment we specifically targeted the more detail-based perception and recognition for greyscale images versus the more gist-based perception and recognition for coloured images with a change detection paradigm. The results show that changes to images are detected faster when image-pairs were presented in greyscale than in colour. This counterintuitive result held for both natural and man-made scenes and thus corroborates the shift from more detailed processing of images in greyscale to more gist-based processing of coloured images.

Although the evidence remains tentative at best, the conception of hallucinations in schizophrenia as being underconstrained perception resulting from intrinsic thalamocortical resonance in sensory areas might complement current models of hallucination. However, in itself, the approach falls short of comprehensively explaining the neurogenesis of hallucinations in schizophrenia, as it neglects the role of external attributional biases, mental imagery, and a disconnection between frontal and temporal areas.

Can we learn without consciousness? When the eminent neuropsychologist, Lawrence Weiskrantz first coined the term 'blindsight' to describe a condition whereby a patient could demonstrate that they were aware of some object, yet insist that they were completely unaware of its existence, the response from some in the scientific community was one of extreme skepticism. Even now, there are those who question the existence of unconscious learning, and the topic remains one of the most actively researched and debated in psychology. (...) In recent years evidence for unconscious processing across a range of sensory modalities have come from studies of vision, audition, memory, emotion, and action. Never before have these studies of unconscious processing in the different senses been brought together into a single volume. In a book dedicated to Lawrence Weiskrantz, some of the leading psychologists and cognitive neuroscientists of the day explain what we know about unconscious processing in the different senses. Including contributions from, amongst others, David Milner, Jon Driver, Alan Cowey, and Ray Dolan, the book presents a state of the art account of what we now know about 'the unconscious'. The book will provide a fascinating account for students and researchers in psychology, cognitive neuroscience, and philosophy. (shrink)

T. S. Eliot left Harvard during his third year of study in the department of philosophy and went to England. Forty-six years later he authorized the publication of his doctoral dissertation. Here we have a reprint of his sympathetic but not entirely uncritical study of the English idealist philosopher F. H. Bradley.

After more than a decade teaching ancient Greek history and philosophy at University College, Oxford, British philosopher and political theorist Bernard Bosanquet resigned from his post to spend more time writing. He was particularly interested in contemporary social theory, and was involved with the Charity Organisation Society and the London Ethical Society. He wrote numerous articles before beginning this book, which was his first and was published in 1885 as a response to the Principles of Logic, published in 1883, by (...) his contemporary F. H. Bradley . Bosanquet, who was deeply influenced by the German philosopher Hegel , argues that there are 'signs of a philosophical movement in this country which may assimilate what is really great in European philosophy, without forfeiting the distinctive merits of English thought'. With this as the framework, the book examines the relationship of judgment and logic to knowledge. (shrink)

F. H. Bradley (1846-1924) was considered in his day to be the greatest British philosopher since Hume. For modern philosophers he continues to be an important and influential figure. However, the opposition to metaphysical thinking throughout most of the twentieth century has somewhat eclipsed his important place in the history of British thought. Consequently, although there is renewed interest in his ideas and role in the development of Western philosophy, his writings are often hard to find. This collection unites all (...) of his published works, much of which has long been out of print, together with selected notebooks, articles, and correspondence from his previously unpublished remains. The set therefore provides the opportunity to view his entire philosophy, both in the breadth of its scope - from critical history and ethics through logic to metaphysics and epistemology - and in its historical development - from the earliest Hegelian writings to the later more psychological and pragmatic work. In addition the set features introductions to Bradley's writings, life and character, providing the framework to assess his permanent importance in the history of philosophy. --the first ever publication of all Bradley's works --includes 5 volumes of reset material, mostly never before published --a collecton that all serious philosophy libraries should have --extremely comprehensive new editorial matter --volumes 4 &amp 5 are indexed by subject and name --collects Bradley's correspondence, spanning 50 years, with Russell, Samuel Alexander, Bosanquet, Haldane, William James, Andrew Seth Pringle-Pattison, and many others --includes Bradley's notes on Green's lectures on ethics, selected undergraduate essays, notebooks preparatory of his major works, lists of what Bradley read, essays that never reached publication, inventory of Bradley's papers, and a catalogue of Bradley's personal library.

Trailblazing marine biologist, visionary conservationist, deep ecology philosopher, Edward F. Ricketts has reached legendary status in the California mythos. A true polymath and a thinker ahead of his time, Ricketts was a scientist who worked in passionate collaboration with many of his friends—artists, writers, and influential intellectual figures—including, perhaps most famously, John Steinbeck, who once said that Ricketts's mind “had no horizons.” This unprecedented collection, featuring previously unpublished pieces as well as others available for the first time in their (...) original form, reflects the wide scope of Ricketts’s scientific, philosophical, and literary interests during the years he lived and worked on Cannery Row in Monterey, California. These writings, which together illuminate the evolution of Ricketts’s unique, holistic approach to science, include “Verbatim transcription of notes on the Gulf of California trip,” the basic manuscript for Steinbeck’s and Ricketts’s _Log from the Sea of Cortez;_ the essays “The Philosophy of Breaking Through” and “A Spiritual Morphology of Poetry;” several shorter pieces on topics including collecting invertebrates and the impact of modernization on Mexican village life; and more. An engaging critical biography and a number of rare photographs offer a new and richly detailed view of Ricketts’s life. (shrink)

The aim of this dissertation is to present a systematic account of F. H. Bradley's philosophy in so far as it is relevant to an understanding of his conception of the nature and criterion of truth. I argue that, for Bradley, the nature of truth is the identity of thought with reality given in immediate experience. There is no absolute separation between thought and its object. Bradley therefore rejects both the correspondence theory and epistemological realism. Thought is not just a (...) mirror which reflects an independently existing reality. ;Concerning the criterion of truth, I argue that his criterion for our ordinary and scientific beliefs is practice, and the criterion for philosophical positions is a kind of coherence based on the doctrine of relative truth. For Bradley, some positions are truer than others, and the best philosophy is a comprehensive system which contains the truth of all different positions. ;Bradley does not accept the coherence theory of justification as it is understood today, since it is based on the standard account of negation and the doctrine of absolute truth. Bradley has a different approach to negation and inconsistency, according to which there are no absolutely inconsistent beliefs. Further, he insists that truth is not absolute but "relative," a matter of degree. All philosophical positions contain some truth, and none is completely false. The truth in philosophy is a position which accounts for the whole of reality and includes all apparently inconsistent positions within it. ;I explain Bradley's place in the history of philosophy and show his connections with the British empiricist tradition. I believe one of Bradley's central concerns is to explain the nature and criterion of truth in philosophy within the constraints of empiricism. I also contrast Bradley's positions on important issues with those of philosophers in the Anglo-American analytic tradition, such as Russell, Moore, Ayer, Tarski, Quine, Churchland, Lehrer and Campbell. I argue that most recent commentators on Bradley overlook the importance of understanding his philosophy as a system constructed according to the doctrine of relative truth. (shrink)

Peer review is an important component of scholarly research. Long a black box whose practical mechanisms were unknown to researchers and readers, peer review is increasingly facing demands for accountability and improvement. Numerous studies address empirical aspects of the peer review process. Much less consideration is typically given to normative dimensions of peer review. This paper considers what authors, editors, reviewers, and readers ought to expect from the peer review process. Integrity in the review process is vital if various parties (...) are to have trust, or faith, in the credibility of peer review mechanisms. Trust in the quality of peer review can increase or diminish in response to numerous factors. Five core elements of peer review are identified. Constitutive elements of scholarly peer review include: fairness in critical analysis of manuscripts; the selection of appropriate reviewers with relevant expertise; identifiable, publicly accountable reviewers; timely reviews, and helpful critical commentary. The F.A.I.T.H. model provides a basis for linking conceptual analysis of the core norms of peer review with empirical research into the adequacy and effectiveness of various processes of peer review. The model is intended to describe core elements of high-quality peer review and suggest what factors can foster or hinder trust in the integrity of peer review. (shrink)

F. H. Bradley: Logic Although the logical system expounded by F. H. Bradley in The Principles of Logic is now almost forgotten, it had many virtues. To appreciate them, it is helpful to understand that Bradley had a very different view of logic from that prevalent today. He is hostile to the idea of … Continue reading Bradley, F. H.: Logic →.

By comparison with the Atlantic Ocean, the physical oceanography of the Pacific was poorly known as late as the end of the 1930s. International collaboration to study the Pacific, attempted by oceanography committees of the Pacific Science Association, was a failure, owing to the scale of the enterprise, the low scientific abilities of the Pacific nations, and the lack of a compelling need. Even in the U.S.A., where the Scripps Institution of Oceanography was active, lack of good ships and personnel (...) reduced the effectiveness of Pacific oceanography. Scripps's physical oceanographer George F. McEwen was more physicist than physical oceanographer; he also became side-tracked into climatology. Only with the arrival of H. U. Sverdrup at Scripps in 1936 did Pacific physical oceanography begin to prosper, but its greatest success followed World War II, when techniques and approaches transplanted from the Atlantic became established.

F. H. Jacobi (1743–1819), a key figure in the philosophical debates at the close of the eighteenth century in Germany, has long been regarded as an irrationalist for allegedly advocating a blind 'leap of faith'. The central claim of this essay is that this venerable charge is misplaced. Following a reconstruction of what a charge of irrationalism might amount to, two of Jacobi's most important works, the "Spinoza Letters" (1785) and "David Hume" (1787), are scrutinized for traces of irrationalism. Far (...) from being an irrationalist, Jacobi is best read as questioning the analytical-geometrical model of rationality popular among his contemporaries, and of proposing a more naturalistic theory of rationality that situates it more firmly in human psychology, the ultimate import of which lies in a reconceptualization of the relation between faith and reason.

Few people now read F.H. Bradley and the British Idealists. This is not because they are not important philosophers. On the contrary. It is generally agreed that Bradley, in particular, 2 is a major philosopher, as well as a great, if demanding, writer. It is rather because Bradley and the other Idealists are thought to inhabit a philosophical world quite different from that of the mainstream of contemporary philosophy. They seem to be concerned with issues and problems which have little (...) or nothing to do with the topics which concern most philosophers nowadays. (shrink)

Abstract It is sometimes thought that Absolute Idealism was undermined by its inability to deal with science. Through a critical discussion of F. H. Bradley's philosophy of science, this idea is challenged. His views on science are divided into a positive and a negative part, and it is argued that, although he found the scientific world view to be essentially false, he was nonetheless able to develop a sympathetic and intelligent philosophy of science. This was basically pragmatic and instrumental in (...) tone, and gave to science a large measure of autonomy from philosophy. His doctrine is connected with certain contemporary ideas in the philosophy of science. (shrink)

We entered upon the work of last session under the heavy cloud occasioned by the loss of Mr. F. H. Bradley, who died only a few days before its opening at the age of seventy-eight; and, in the midst of that session, on March 4th, Professor James Ward passed away at the ripe age of eighty-two years. Thus the two foremost English philosophers of our time have been removed from our midst; and it seems fitting that, in commencing the duties (...) of this new session, I should say something about their contributions to our common pursuit, and try to indicate what we owe to them who have been for so long the leaders of philosophical research in this country.
